Photovoltaic Cells – Technology of the Future
“ Photovoltaic cells ” are referred to as “the fastest growing technology companies in the world.” They are one of the smartest inventions created by man, because they use the energy that is provided for “free” by nature. The sun continues to shine for millions of years and as efficient solar panels or photovoltaic cells, then people free and clean energy for years to come. In this article I try to write about everything you need to know from photovoltaic cells.
In principle, photovoltaic cells have been constructed with the aid of different forms of the silicon element such as crystalline and amorphous silicon. Also, given the growing demand for the solar energy industry and the expected future growth, it has become necessary that the photovoltaics industry remains in step with the growth. Therefore, there have been a lot of research and testing done to try and improve the efficiency of photovoltaic cells
Most of the solar panels or solar panels have capacities ranging anywhere from 20 -. 50 MW. The solar panels are expected to be devised in the future that the capacity of over 100 MW. The problem that most people have when setting up solar panels or solar installations is that the original production costs are quite high. But with all the awareness is spread about solar energy, people have come to know that they can by easily overcoming these cost wait for a few years, after which they will have saved enough money on electricity bills.
Also, using the ideal source of energy for heating purposes. Solar water heaters on a rise shops and more and more people are starting to buy them.
Let me try to explain to you in scientific terms how these photovoltaic cells. In short, what happens is that when the photon particles from the sun will be the surface of the silicon molecule or plates which consist of silicon or boron-silicon-phosphorus, there are two opposite charges created because the photons excite the electrons. This excitation of the electrons leave the electron to be pushed to a higher level. Eventually, the excited electrons kicked out of the atom. For example, a plate is a “shortage of electrons,” and the other has excess electrons. This makes it possible for the conduction of electricity. The oppositely charged plates have flow of electrons through it. This is the operating principle of a solar cell or photovoltaic cell.
Thus, if comparable, these solar cells, or PV are combined, results in the formation of higher plants electricity capacity. They are ideally used in satellites where there is no electrical lines to offer unlimited power supply to them. Also, they are used in a much smaller scale in smaller devices such as watches and calculators.
One problem that people face with solar panels and photovoltaic cells is that they produce direct current while the electrical appliances that we needed use in our homes alternating current. So using a converter is also needed.
Solar energy is also a major industry that has the potential to create many jobs. There is already creating thousands of jobs in places like Germany and India and the US, all three countries with plenty of solar energy into electricity.
Other applications, such as solar-powered cars are solar powered seizure robots and gadgets are also on the rise and finally, I can say that this market has a huge potential to make it big.
